[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-5 This utility model provides a technical solution for a heat shrink packaging machine for high-end cigarette boxes: It includes a frame 1, with support plates 101 symmetrically installed at the front end of the top surface of the frame 1. Rotating rollers 102 are symmetrically mounted between the two support plates 101. A conveyor belt 103 is rotatably connected to the two rotating rollers 102. A power component installed on the outer wall of the support plates 101 drives the two rotating rollers 102 to rotate the conveyor belt 103, thereby conveying the cigarette boxes to be heat-shrinked placed on the conveyor belt 103. A heat shrink machine 104 (a conventional technology, whose working principle is not described here) is bolted to the rear end of the top surface of the frame 1. The heat shrink machine 104 has a through-type inlet 105 and an outlet on its front and rear outer walls, respectively. 106. Several rotating rollers 107 are installed inside the heat shrink machine 104. Heat insulation curtains 402 are provided on the inner sides of the inlet 105 and outlet 106 (the heat insulation curtains 402 can reduce heat loss inside the heat shrink machine 104). The power component 2 on the outer wall of the heat shrink machine 104 can drive the several rotating rollers 107 to rotate synchronously and in the same direction. When the conveyor belt 103 conveys the cigarette packaging box to be heat-shrinked along the inlet 105 into the heat shrink machine 104, it is conveyed again by the rotating rollers 107. During the conveying process, the heat shrink machine 104 heat shrinks the cigarette packaging box. During the process, the heat shrinking of the cigarette packaging box can be observed in real time through the transparent window plate provided on the outer wall of the heat shrink machine 104, which is convenient for timely adjustment.
[0027] A guide assembly 2 is provided at the front end of the outer top surface of the two support plates 101. The guide assembly 2 includes push plates 201 symmetrically arranged on the conveyor belt 103. Grooves 202 are provided on the outer wall of the corresponding side of the two push plates 201. Several pulleys 203 are rotatably installed inside the two sets of grooves 202 (the pulleys 203 ensure the smooth conveying of cigarette packaging boxes during the limiting and guiding process). Square plates 204 are fixedly connected to the outer wall of the opposite side of the two push plates 201 by bolts (the bolt connection method facilitates replacement). A housing 205 is fixedly installed on the inner top surface of the frame 1 by bolts. A connecting rod 206 is rotatably installed inside the housing 205. The two ends of the connecting rod 206 extend rotatably to the outer walls of the left and right sides of the housing 205, and the outer peripheral surfaces of both ends are threaded (the threads at both ends run in opposite directions). The outer walls of the left and right ends of the connecting rod 206 are threaded with... Square sleeves 207, vertical plates 208 are fixed on opposite outer walls of the two square sleeves 207, the two vertical plates 208 are fixedly connected to the two square plates 204, a worm gear 209 is fixedly installed inside the housing 205 and on the outer wall of the connecting rod 206, a worm 210 is rotatably installed on the inner wall of the housing 205 and below the worm gear 209, a drive motor 211 is fixedly installed on the front outer wall of the housing 205, one end of the worm 210 extends rotatably to the outside of the housing 205 and is fixedly connected to the output end of the drive motor 211, the worm gear 209 and the worm 210 are meshed, a spiral sleeve 4 is symmetrically installed at both ends of the inner top surface of the frame 1, the outer walls of the two square sleeves 207 are slidably fitted into the inner sides of the two spiral sleeves 4, a spiral sleeve 401 is fixedly installed on the outer top surface of the two support plates 101, the outer walls of the two square plates 204 are slidably fitted into the inner sides of the two spiral sleeves 401. When the cigarette packaging boxes to be heat-shrinked are placed on the conveyor belt 103 for conveying, the drive motor 211 can be controlled and started to drive the worm gear 210 to drive the worm wheel 209 to rotate inside the housing 205. This allows the connecting rod 206 to drive the two sets of square sleeves 207 to move relative to each other along the inside of the first loop sleeve 4, moving away from or closer to each other. This allows the vertical plate 208 to drive the square plate 204 to move synchronously relative to each other inside the second loop sleeve 401. This allows the push plate 201 to limit and guide cigarette packaging boxes of different sizes to avoid deviation. At the same time, after the distance between the two push plates 201 is adjusted, the worm gear 210 is locked by the shaft locking device installed on the front outer wall of the housing 205 to prevent self-rotation.
[0028] A heat-cutting assembly 3 is provided at the rear end of the outer top surface of the two support plates 101. The heat-cutting assembly 3 includes a connecting plate 301 fixed to the rear end of the outer top surface of the two support plates 101 by bolts, a top plate 302 fixed together on the outer top surface of the two connecting plates 301, a movable plate 303 provided on the outer bottom surface of the top plate 302 and located between the two connecting plates 301, a U-shaped frame 304 fixed to the outer bottom surface of the movable plate 303 by bolts, and a heat-sealing mold frame 305 (for pressing the four corners of the cigarette packaging box and for easy replacement of corresponding parts as needed) fixed to both ends of the outer bottom surface of the U-shaped frame 304 by bolts. A protective ring layer 306 is symmetrically provided on the outer bottom surface of the heat-sealing mold frame 305, and a heat-sealing knife 307 (existing) is installed between the two protective ring layers 306. (The working principle of this conventional technical method will not be elaborated in the text.) An electric push rod 308 is fixedly installed at the center of the outer top surface of the top plate 302. The output end of the electric push rod 308 extends to the outer bottom surface of the top plate 302 and is fixedly connected to the moving plate 303. A through-type sliding groove 309 is opened on the outer side wall of both connecting plates 301. The two ends of the moving plate 303 are slidably connected to the inner side of the two sliding grooves 309 respectively. When the cigarette packaging box is stably conveyed to the bottom of the heat sealing mold frame 305, the electric push rod 308 is controlled and activated to drive the moving plate 303 to move steadily downward along the sliding groove 309. The transparent film on the outside of the cigarette packaging box is stably pressed and released by the protective ring 306, which facilitates the heat sealing knife 307 to heat seal the transparent film, thereby improving practicality.
[0029] The working principle of this utility model is as follows: When in use, the cigarette packaging box to be heat-shrinked is first placed on the conveyor belt 103. Then, the drive motor 211 is started to drive the worm gear 210 to drive the worm wheel 209 to rotate inside the housing 205. This causes the connecting rod 206 to drive the two sets of square sleeves 207 to move relative to each other along the inside of the first loop sleeve 4. This causes the vertical plate 208 to drive the square plate 204 to move synchronously inside the second loop sleeve 401. The pulley 203 on the push plate 201 limits and guides the cigarette packaging box.
[0030] Simultaneously, the conveyor belt 103 is activated to transport the cigarette packaging box to the bottom of the heat sealing mold frame 305. Then, the electric push rod 308 is activated to drive the moving plate 303 to move downward. The protective ring 306 presses down the transparent film on the outside of the cigarette packaging box, and then the heat sealing knife 307 heat seals the transparent film.
[0031] At the same time, the conveyor belt 103 transports the heat-sealed cigarette packaging box along the feed port 105 to the heat shrink machine 104. After passing through the rotating roller 107, it is transported again, and the heat shrink machine 104 heat shrinks the cigarette packaging box during the transport process.
[0032] Finally, the heat-shrink cigarette packaging boxes are discharged and collected through the discharge port 106.
[0033] It should be noted that power components one and two are existing technologies, and their working principles will not be described in detail in this article. All electrical components mentioned in this article are electrically connected to the controller and the power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming.
